fix: address AI code review - probe defaults to no audio, safe af filter

- render_audio.py: simple mode builds af_parts list then joins into single -af (defensive against future multi-clip) - unified_render_service.py: probe_has_audio exception now defaults to False with warning log (was unsafe True) - test: add test_pass_through_probe_exception_defaults_to_no_audio
